The Last Thing Mary saw is a horror film about two star crossed women in love living in an 1800s traditional Christian household. We begin on Mary , bleeding for the eyes reciting the Lord's Prayer in front of men with guns drawn , and head back in time to see how we got there.
This movie is intentionally made to be a very slow burn and in-fact you could sum up this movies entire plot in about 2-3 sentences.
While there is a "twist" so to speak the movie is not a twisty-turny ride of intrigue and it's more about putting you in the shoes of our protagonists fighting an uphill battle in a "backwards" time. Some of it honestly works. Most of it is just too painfully slow with tons of frustrating scenes with that had so much potential. One scene with Rory Culkin's character was setting up to be fantastic, shocking and then it just kind of ends.
The movie isn't awful but it also really lacks a lot of high points that make movies stand up to me. It won't be the worst movie you watch but it also won't be memorable after it wears off.
